More examples in the documentation would probably help.
When you say -f takes a file, it is difficult to know whether that
means /dev/hda or something like /usr/templates/IBM_master_template.gz
since everything in Unix is a file.
It is whatever you want to clone. In your case, it seems to be the
template file that you want to send.
In the case of udp-receiver on the server, I'd
think it should be
something like /usr/templates/IBM_master_template.gz
I think you mean udp-sender on the server ...
Now the reverse trip, to make the clones...
The server would run something like:
udp-sender -f /usr/templates/IBM_master_template.gz --min-clients 20
(assuming i want it to start after all 20 machines have connected)
while the target machines would boot a floppy or off the PXE to
launch the receiver built into it.
Do I have this right?
I've not used the floppy because it doesn't come with my SCSI driver,
but you want the target file on the client to be something like
/dev/hda. You'll also want to uncompress that image file before you
send it, unless you're just trying to transfer the image itself as a file.
It is partly difficult to understand because of the
floppy menu not forming a visible part of the udpcast
source package and man pages. Coming from the g4u I am
expecting a shell script and executables on the floppy,
but I have yet to run it.
You have yet to run the floppy? It asks you what to do...

[A] above implies that if there is a 'sender' option on the floppy,
there is probably also a 'receiver' option. This is the one you'd want.
On the server, I think you have the basic idea down. Again, not
having used the floppy, I don't know if you can have the floppy
udp-receiver pipe through gunzip before writing. You'll have to try it
and see.
